Array Classes

I have defined a class called order and definied a new variable using this class (as an array).

class order
{
var $pr_code;
var $pr_quan;
}

$ord_item = array();
$ord_item[] = new order

Now that I've defined these, I want to save the information into the variable class.

So far I'm looking at the following code:

array_push($ord_item, $ord_item->pr_code = $pr_code, $ord_item->pr_quan = $pr_quan);

I have not tried this code as it does not look right. Is there a certain way of adding a new order to the end of the array and store both class values?!

Assistance Would Be Great
